[ 2I .+ ] 
When a ftranger, from botanical or other curiofity* 
goes to the top of a Welfh mountain, he is obliged 
to truft implicitly to his guide, who contrives to carry 
him where he can ride on horfeback. *1 he ftranger 
therefore proceeds in the very track, where a fheep of 
cow can graze, which confequentlycrop the flowering 
Item and leaves of the plants. 
It is in the fifliires of rocks, and the central parts of 
bogs, that the fearch for uncommon plants muft be 
made ; he who looks elfewhere for them, -may travel 
a great deal of ground, but will never make any mate- 
rial difcoveries. 
I will not detain you longer with obfervations of 
this kind; as they muft have been to you long obvious 
and familiar. I have, however, been infenflbly be- 
trayed into this length, by thinking, that every at- 
tempt to render the natural Hiftory of Great Britain 
more complete, and accurate, may not be entirely 
without its ufe. 
I am, 
Dear Sir, 
Your moft faithful 
Humble fervant, 
Daines Barrington.
